Button menu for "Application menu" displayed on title bar for "Window decorations" different than Breeze and Plastik is the same like button "Menu", placed usually in left corner of title bar. In System Settings: "Window decorations -> Buttons" at the left side of title bar preview I have two buttons: "Menu" and "Application menu". And in Theme I see that hamburger menu ("Application menu") is placed only on "Breeze" and "Plastik". On others (Oxygen, FormaN, Chrome dark) I see two the same icons - "Menu". Does it mean that "Application menu" looking like "hamburger menu" is supported only for "Breeze" and "Plastik" window decorations?

Hello, Thanks for reporting. Most likely an oxygen bug, (choosing the same visual appearance for the menu and appmenu button). Will investigate asap.
Thank you for reporting this issue in KDE software. As it has been a while since this issue was reported, can we please ask you to see if you can reproduce the issue with a recent software version? If you can reproduce the issue, please change the status to "REPORTED" when replying. Thank you!
For decoration other than Breeze, the button related with appmenu looks like "More actions for this window". I tested with following decorations: "air-oxygen", "FormaN" and "Freeze". Please notice all of them are not provided by KDE/Plasma but are coming from users. I'm not sure if these buttons are provided by specified "Window Decoration" created by user or are delegated by KDE. Anyway correct behavior I observed only for Breeze.
I noticed that mentioned button looks correctly also in theme: "Plastic" Tested with: Operating System: KDE neon Unstable Edition (updates coming from today's [29/11/2022] morning) KDE Plasma Version: 5.26.80 KDE Frameworks Version: 5.101.0 Qt Version: 5.15.7 Kernel Version: 5.15.0-53-generic (64-bit) Graphics Platform: X11 Graphics Processor: Mesa Intel® Xe Graphics
